Description

用來容納工具之鏈匣、具有此鏈匣的機床及此鏈匣的用途 Chain box for accommodating tools, machine tool with the chain box and use of the chain box

本發明涉及一種如請求項1的標的所述的用來容納工具的鏈匣。 The present invention relates to a chain box for accommodating tools as described in the subject of claim 1.

這種鏈匣用於提供大量被需要用於機床的不同的加工目的的工具。例如借助於雙夾具實現機床處的工具替換，在所述雙夾具的兩個臂端部處分別能夠容納有一個工具。如果所述雙夾具旋轉，用以從所述鏈匣中取出工具或者將工具引入鏈匣中，那麼會發生與相鄰的工具碰撞。這能夠藉由以下方法得到防止，即在工具容納部之間設置足夠大的間距，從而為抓取給出足夠的空間，例如參見申請EP 2 308 637 A2。然而這種結構具有以下缺點，即鏈匣具有相對體積較大的結構。 Such chain magazines are used to provide a large number of tools that are required for different machining purposes of machine tools. For example, the tool replacement at the machine tool is realized by means of a double clamp, and a tool can be accommodated at each of the two arm ends of the double clamp. If the double jig rotates to remove a tool from the chain box or introduce a tool into the chain box, collision with an adjacent tool may occur. This can be prevented by setting a sufficiently large distance between the tool receptacles to give enough space for gripping, see for example application EP 2 308 637 A2. However, this structure has the disadvantage that the chain box has a relatively large structure.

從申請EP 0 636 056 A1中公開了，分別藉由兩個徑向敞開地設計的套形成工具容納部。由此，藉由在 鏈在其中延伸的平面中移動能夠取出或者能夠引入工具。然而，要設置專門的措施，其防止工具會在其相對於工具容納部存儲時落下。這使得鏈匣的結構相對複雜。 From application EP 0 636 056 A1, it is disclosed that the tool receptacle is formed by two radially open sleeves, respectively. Thus, by The movement of the chain in the plane in which the chain extends can be taken out or the tool can be introduced. However, special measures are to be provided that prevent the tool from falling when it is stored relative to the tool housing. This makes the structure of the chain box relatively complicated.

從所述現有技術出發，本發明的目的基於提出如下的鏈匣，其具有更緊湊的結構。 Proceeding from the aforementioned prior art, the object of the present invention is based on proposing a chain box having a more compact structure.

解決所述目的的鏈匣在權利要求1中得到說明。其它的權利要求說明了特別的實施方式以及具有鏈匣的機床和其應用。 The chain box that solves the object is described in claim 1. The other claims describe particular embodiments and machine tools with chain boxes and their applications.

所述鏈匣能夠藉由引導機構的設置而設計成緊湊的，所述引導機構具有在第一和第二位置之間能夠來回運動的引導元件，借助於所述引導元件能夠轉出和轉入鏈節的工具容納部。在工具容納部的轉出的位置中能夠實現側向的空間，用以實現例如夾具的無碰撞的抓取。所述引導機構允許簡單地並且快速地裝入和取出工具。 The chain magazine can be designed to be compact by the arrangement of a guide mechanism having a guide element that can move back and forth between the first and second positions, by means of which the guide element can be turned out and in Tool accommodating part of the chain link. In the turned-out position of the tool receptacle, a lateral space can be realized for collision-free gripping of, for example, a clamp. The guide mechanism allows simple and quick loading and unloading of tools.

所述引導元件優選具有兩個用於工具容納部的容納部空間並且能夠圍繞擺動軸線擺動，所述擺動軸線與佈置在引導元件中的鏈節的鉸接軸線重合。該設計方案實現了鏈匣的特別簡單的結構。 The guide element preferably has two receptacle spaces for the tool receptacle and can be swiveled about a pivot axis which coincides with the hinge axis of the chain link arranged in the guide element. This design solution realizes a particularly simple structure of the chain box.

The diagram shows: FIG. 1 is a side view of the chain cassette in the original position, FIG. 2 is the chain cassette in FIG. 1 with the chain link turned out, and FIG. 3 is a side view of the guide mechanism for the chain cassette in FIG. The mechanism has a static and swingable guide element, FIG. 4 is a view according to FIG. 3, wherein the swingable guide element is in the swing position, FIG. 5 is an end view of the static guide element in FIG. 3, and 6 is a swingable guide element taken along the line VI-VI of FIG. 3.

圖1示出了具有連續地環繞的鏈1的鏈匣，該鏈具有相互鉸接地連接的鏈節2、3。鏈節2包含第一和第二工具容納部2a、2b，其分別用來容納工具5並且例如構造成容納袋(Aufnahmeköchers)的形式。相應的工具容納部2a、2b設有鉸接部，使相鄰的鏈節2相互連接的連接節3耦聯到所述鉸接部處。鏈節2關於耦聯在其處的連接節3能夠圍繞軸線X擺動，該軸線延伸穿過工具容納部2a或者說2b並且垂直於YZ平面，所述鏈1作為整體能夠在YZ平面中環繞地運動。在按圖1的圖示中，軸線X垂直於圖紙平面。工具容納部2a、2b環繞地構造，從而能夠藉由沿軸線X的移動來取出或者引入工具。 FIG. 1 shows a chain magazine with a continuously surrounding chain 1 with chain links 2, 3 hingedly connected to each other. The chain link 2 includes first and second tool receptacles 2a, 2b, which are used to receive the tool 5 and are configured, for example, in the form of pockets. Corresponding tool accommodating portions 2a, 2b are provided with hinged portions, and the connecting links 3 connecting adjacent chain links 2 to each other are coupled to the hinged portions. The chain link 2 can swing about an axis X with respect to the connecting link 3 coupled thereto, which extends through the tool receptacle 2a or 2b and is perpendicular to the YZ plane, the chain 1 as a whole can be encircled in the YZ plane movement. In the illustration according to FIG. 1, the axis X is perpendicular to the plane of the drawing. The tool receptacles 2a, 2b are constructed circumferentially so that the tool can be taken out or introduced by movement along the axis X.

所述鏈1在該實施例中圍繞兩個鏈輪6、7延伸。可以考慮僅僅在所述一個偏轉部位中設置鏈輪，而另 外的偏轉部位藉由靜態的引導元件形成，鏈1能夠藉由所述引導元件滑動並且所述引導元件例如具有特別光滑的並且穩定的表面。此外，如下的實施例也是可行的，其中所述鏈1圍繞三個、四個或更多個鏈輪延伸，用以形成具有兩個以上的偏轉部位的軌道。 The chain 1 extends around two sprockets 6, 7 in this embodiment. It can be considered that only one sprocket is provided in the one deflection site, and another The outer deflection point is formed by a static guide element by which the chain 1 can slide and the guide element has a particularly smooth and stable surface, for example. In addition, the following embodiment is also possible, in which the chain 1 extends around three, four, or more sprockets to form a track having more than two deflection sites.

相應的鏈輪6、7具有與鏈1處於嚙合中的齒6a、7b。至少一個所述鏈輪、在此是鏈輪6是能夠驅動的，並且為此目的與(沒有示出的)鏈式驅動機構連接。如下面還要解釋的那樣，設置了能夠切換的偏轉部位，使得鏈1的軌道的尺寸是可變的。為了補償這種變化，所述鏈輪中的至少一個不僅能夠轉動地而且也能夠移動地得到支承。由此能夠獨立於所述的偏轉部位的切換狀態確保所述鏈1保持足夠張緊並且鏈輪足夠地嚙合到鏈1中始終被給出。 The corresponding sprockets 6, 7 have teeth 6a, 7b in mesh with the chain 1. At least one of the sprockets, here the sprocket 6, can be driven and is connected to a chain drive (not shown) for this purpose. As will be explained below, a switchable deflection point is provided so that the size of the track of the chain 1 is variable. To compensate for this change, at least one of the sprockets is supported not only rotatably but also movably. This makes it possible to ensure that the chain 1 remains sufficiently tensioned and that the sprocket is sufficiently engaged into the chain 1 independently of the switching state of the deflection point.

在該實施例中，鏈輪7的軸線7b(鏈輪圍繞該軸線能夠轉動)能夠沿著Y軸線來回移動地支承。由此能夠改變鏈輪6和7之間的間距。具有靜態地裝配的殼體8a以及能夠移動的調節桿8b的線性驅動機構8用於移動所述鏈輪7，所述調節桿耦聯到鏈輪7的軸線7b處。例如能夠使用氣動的驅動機構作為線性驅動機構8。 In this embodiment, the axis 7b of the sprocket 7 about which the sprocket can turn can be supported to move back and forth along the Y axis. As a result, the distance between the sprockets 6 and 7 can be changed. A linear drive mechanism 8 with a statically assembled housing 8a and a movable adjustment lever 8b is used to move the sprocket 7 and the adjustment lever is coupled to the axis 7b of the sprocket 7. For example, a pneumatic drive mechanism can be used as the linear drive mechanism 8.

在圖1中還示出了用於鏈1的引導機構9-12。在此，所述引導機構包括作用到鏈1的按圖1在上面的支線1a上的引導元件9、10以及作用到鏈1的按圖1在下面的支線1b上的引導元件11、12。所述引導元件 9、10構造成導軌的形式，鏈1在所述導軌之間延伸穿過。如下地設計在圖1中所示的裝置，使得Z軸線沿著豎直線延伸並且由此重力沿著該軸線作用。在此如下地設計所述引導導軌10，使得其連同引導也適合於支撐所述鏈1以及容納在其中的工具5。根據應用情況，所述鏈匣也可以以其它定向進行佈置。相應地，相應的引導元件9、10不同地設計、補充或者可能完全略去。 The guide mechanism 9-12 for the chain 1 is also shown in FIG. In this case, the guide mechanism comprises guide elements 9, 10 acting on the upper branch 1 a of FIG. 1 on the chain 1 and guide elements 11, 12 acting on the lower branch 1 b of FIG. 1 on the chain 1. The guide element 9, 10 are constructed in the form of rails between which the chain 1 extends. The device shown in FIG. 1 is designed such that the Z axis extends along a vertical line and thus gravity acts along this axis. The guide rail 10 is designed in such a way that it, together with the guide, is also suitable for supporting the chain 1 and the tool 5 accommodated therein. Depending on the application, the chain box can also be arranged in other orientations. Correspondingly, the corresponding guide elements 9, 10 are designed differently, supplemented or may be completely omitted.

所述引導元件11佈置並且設計成靜態的，從而鏈支線1b關於所述引導元件12的位置得到確定，所述引導元件能夠擺動地設計並且為此目的耦聯到(沒有示出的)驅動機構處。所述引導元件12的擺動軸線12c沿著鏈節2的軸線X的方向指向。所述引導元件12用作能夠切換的偏轉部位，從而能夠轉出任意的鏈節2並且由此能夠轉出工具容納部2a或2b，用以使其為了操作所述工具5更好地接近。 The guide element 11 is arranged and designed to be static, so that the position of the chain branch 1b with respect to the guide element 12 is determined, which can be pivotally designed and is coupled to a drive mechanism (not shown) for this purpose Office. The pivot axis 12 c of the guide element 12 points in the direction of the axis X of the chain link 2. The guide element 12 serves as a switchable deflection point, so that any chain link 2 and thus the tool receptacle 2 a or 2 b can be turned out for better access for operating the tool 5.

所述引導元件12具有第一容納部空間12a和第二容納部空間12b，工具容納部2a或2b能夠定位在所述第一容納部空間處，相鄰的工具容納部2b或者說2a能夠定位在所述第二容納部空間處。第一容納部空間12a與定位在那裡的工具容納部2a或2b一起能夠轉出和轉入，而第二容納部空間12b與定位在那裡的工具容納部2b或者說2a一起能夠圍繞擺動軸線12c擺動。在按圖1的圖示中，兩個容納部空間12a、12b由同一個鏈節2的工具容納部2a、2b佔據，從而所述工具容納部2a能夠轉出和 轉入。如果要轉出和轉入工具容納部2b，那麼在兩個容納部空間12a、12b中的工具容納部2a、2b就屬於兩個相鄰的鏈節2。 The guide element 12 has a first receptacle space 12a and a second receptacle space 12b, the tool receptacle 2a or 2b can be positioned at the first receptacle space, and the adjacent tool receptacle 2b or 2a can be positioned At the second accommodation space. The first receptacle space 12a can be swiveled in and out together with the tool receptacle 2a or 2b positioned there, while the second receptacle space 12b can surround the pivot axis 12c together with the tool receptacle 2b or 2a positioned there swing. In the illustration according to FIG. 1, the two receptacle spaces 12 a, 12 b are occupied by tool receptacles 2 a, 2 b of the same chain link 2, so that the tool receptacle 2 a can be turned out and Transfer in. If the tool receptacle 2b is to be turned out and in, the tool receptacles 2a, 2b in the two receptacle spaces 12a, 12b belong to two adjacent chain links 2.

在能夠切換的偏轉部位中存在有交付站15，工具5在所述交付站處能夠從工具容納部2a、2b中取出或者能夠引入到工具容納部中。 In the switchable deflection point, there is a delivery station 15 where the tool 5 can be taken out of the tool receptacle 2a, 2b or can be introduced into the tool receptacle.

所述引導元件12能夠以其擺動的角度根據鏈匣的應用目的設計並且能夠為至少20度、優選至少30度、並且特別優選至少40度。 The guide element 12 can be designed with its swing angle according to the application purpose of the chain magazine and can be at least 20 degrees, preferably at least 30 degrees, and particularly preferably at least 40 degrees.

在按圖1的實施例中，下面的鏈支線1b具有不直的走向，從而在引導元件12的沒有轉出的原始位置中已經給出了容納在容納部空間12a、12b中的工具容納部2a、2b的偏移。在圖1中藉由虛線W說明了藉由與其相鄰的工具容納部的中心延伸的軸線。容納部空間12a中的工具容納部2a相對於軸線W具有偏移w1，容納部空間12b中的工具容納部2b具有偏移w2。所述鏈支線1b的這種不直的走向以及由此工具容納部2a、2b的偏移使得在沒有轉出的原始位置中就已經實現了額外的空間，用以使得無碰撞地進入變得容易。 In the embodiment according to FIG. 1, the lower chain branch line 1 b has an uneven course, so that in the original position of the guide element 12 that has not been turned out, the tool receptacle is accommodated in the receptacle space 12 a, 12 b 2a, 2b offset. In FIG. 1, the broken line W illustrates the axis extending through the center of the tool receiving portion adjacent thereto. The tool accommodating portion 2a in the accommodating portion space 12a has an offset w1 with respect to the axis W, and the tool accommodating portion 2b in the accommodating portion space 12b has an offset w2. The non-straight course of the chain branch line 1b and the offset of the tool receptacles 2a, 2b thus allow additional space to be achieved in the original position without turning out, so that collision-free entry becomes possible easy.

如在圖2中所示的那樣，在如下的位置中獲得了特別多的空間，在其中引導元件12位於擺動的位置中。具有所希望的工具5的工件容納部、在此2a被轉出並且位於交付站15中。兩個相鄰的工件容納部、在此2b之間的間距被縮短，這藉由沿Y方向移動鏈輪7進行補 償。工件容納部的轉出使得所述工件容納部橫向於運動方向Y移動，鏈支線1b能夠沿著該運動方向運動，由此側向於轉出的工件容納部實現特別環繞的空間，從而實現例如夾具的無碰撞的抓取。 As shown in FIG. 2, a particularly large amount of space is obtained in the position in which the guide element 12 is in the pivoted position. The workpiece receptacle with the desired tool 5 is here turned out 2a and is located in the delivery station 15. The distance between two adjacent workpiece receiving portions, 2b, is shortened, which is compensated by moving the sprocket 7 in the Y direction Pay. The turning-out of the workpiece receiving portion causes the workpiece receiving portion to move transversely to the direction of movement Y, along which the chain branch line 1b can move, whereby a laterally surrounding space for the turned-out workpiece receiving portion realizes, for example, Collision-free gripping of the fixture.

圖3和4示出了沒有鏈1的引導元件11、12。相應的引導元件11、12具有引導通道11d或者12d(也參照圖5和6)。在運行中，鏈1的工具容納部2a、2b與容納在其中的工具5一起穿過引導通道11d、12d移動。如從圖3中看出的那樣，所述引導通道11d、12d在引導元件12的沒有轉出的狀態中形成了連續的通道，所述連續的通道具有偏移的中間區段並且所述連續的通道由此與筆直的走向不同。由此獲得了工具容納部的上面所提到的偏移w1和w2，所述工具容納部位於容納部空間12a或者12b中。根據使用目的也可以考慮略去所述偏移的設計並且如下地設計所述引導通道11d、12d，從而獲得具有筆直的走向的通道。 3 and 4 show the guide elements 11, 12 without the chain 1. The corresponding guide elements 11, 12 have guide channels 11 d or 12 d (see also FIGS. 5 and 6 ). In operation, the tool receptacles 2a, 2b of the chain 1 move through the guide channels 11d, 12d together with the tool 5 contained therein. As can be seen from FIG. 3, the guide channels 11 d, 12 d form a continuous channel in the state where the guide element 12 is not turned out, the continuous channel has an offset middle section and the continuous The passage of is therefore different from the straight direction. This results in the above-mentioned offsets w1 and w2 of the tool receptacle, which is located in the receptacle space 12a or 12b. Depending on the purpose of use, it is also conceivable to omit the design of the offset and design the guide channels 11d, 12d as follows, so as to obtain a channel with a straight course.

所述鏈匣的運行例如如下：所述鏈1如下遠地運動，直到具有所希望的工具5的工具容納部2a、2b位於引導元件12的第一容納部空間12a處。在第二容納部空間12b中佈置有與之相鄰的工具容納部2a、2b，從而其軸線X與擺動軸線12c重合。在操作所述引導元件12時，在第二容納部空間12b中的工具容納部2a、2b圍繞擺動軸線12c轉動。同時，所述工具容納部2a、2b在第一容納部空間12a中轉出並且存儲 在其中的工具5對於操作機構來說變得可接近。為了實現轉出，所述鏈輪7沿Y方向移動。 The operation of the chain magazine is, for example, as follows: The chain 1 moves remotely as follows until the tool receptacles 2a, 2b with the desired tool 5 are located in the first receptacle space 12a of the guide element 12. In the second accommodating portion space 12b, the tool accommodating portions 2a, 2b adjacent thereto are arranged so that the axis X thereof coincides with the swing axis 12c. When operating the guide element 12, the tool receptacles 2 a, 2 b in the second receptacle space 12 b rotate about the pivot axis 12 c. At the same time, the tool accommodating portions 2a, 2b are turned out and stored in the first accommodating portion space 12a The tool 5 therein becomes accessible to the operating mechanism. In order to realize the roll-out, the sprocket 7 moves in the Y direction.

所述操作機構例如包括雙夾具，其具有能夠旋轉的槓桿，在所述槓桿的兩個端部處分別佈置有用來容納工具的夾具。在按圖2的實施例中使用時，雙夾具能夠圍繞X軸線轉動以及能夠沿著X和Z軸線行移。所述雙夾具如下地行移，使得所述一個夾具能夠抓住在交付站15中的工具5。藉由所述夾具沿X軸線並且由此軸向於工件容納部12a、12b移動實現了從鏈匣中取出工具5。隨後轉動所述雙夾具、典型地轉動180度，使得所述另一夾具與交付站15中有待存儲的工具進入平放。藉由軸向的移動，所述工具最後被引入工件容納部12a、12b。 The operating mechanism includes, for example, a double jig having a lever capable of rotation, and jigs for accommodating tools are arranged at both ends of the lever, respectively. When used in the embodiment according to FIG. 2, the double clamp can rotate around the X axis and can travel along the X and Z axes. The double jig moves as follows, so that the one jig can grasp the tool 5 in the delivery station 15. The tool 5 is removed from the chain magazine by the movement of the jig along the X axis and thus the workpiece receptacles 12a, 12b. The double jig is then turned, typically 180 degrees, so that the other jig and the tool in the delivery station 15 to be stored enter flat. By the axial movement, the tool is finally introduced into the workpiece receiving portions 12a, 12b.

所述鏈匣允許緊湊的設計並且能夠多種多樣地進行使用，例如在用於切屑加工的機器中，用以有效地更換工具。 The chain magazine allows a compact design and can be used in a variety of ways, for example in a machine for chip machining, to effectively change tools.

從前面的描述中，本領域技術人員可以獲得大量變型方案，而沒有離開本發明的、藉由請求項界定的保護範圍。 From the foregoing description, those skilled in the art can obtain a large number of variations without departing from the scope of protection of the present invention defined by the claims.

在圖式中所示的例子中，所述引導元件12構造成能夠擺動的。也可以考慮其它運動形式，用以使得引導元件在第一和第二位置之間來回運動並且由此使工具容納部轉出和轉入。例如所述引導元件能夠線性能夠移動地佈置。為此目的，例如在按圖1的實施方式中，代替引導元件12設置有耦聯到驅動機構處的並且沿Z軸線能夠線 性地來回移動地佈置的引導元件，從而-類似於按圖2的圖示-所述工具容納部2a能夠被轉出並且用於裝入和移出工具5的空間被側向地實現。 In the example shown in the drawing, the guide element 12 is configured to be swingable. Other forms of movement are also conceivable to move the guide element back and forth between the first and second positions and thereby turn the tool receptacle out and in. For example, the guide element can be arranged linearly and movably. For this purpose, for example, in the embodiment according to FIG. 1, instead of the guide element 12, a coupling to the drive mechanism and a line along the Z axis is possible The guide elements are arranged to move back and forth, so that-similar to the illustration according to FIG. 2-the tool receptacle 2a can be swiveled out and the space for inserting and removing the tool 5 is realized laterally.
